Doesn't it have one of those weird 4 pin ARINC plugs that you need an
adapter for (a-la http://tinyurl.com/2erxr6 ) in the center pedestal?

I would think that it should, and if it does, the adapter for cigarette
plugs will be a lot cheaper than having one installed.

SPORTY'S sells the 12V adaptor that fits the four-pin receptacle.
